[PATCh v3 0/8] arm64: dts: renesas: Add RZ/G3E audio enablement
From: John Madieu
Date: Thu Apr 02 2026 - 12:41:41 EST
Add device tree support and board enablement for audio on the
RZ/G3E SMARC EVK with a Dialog DA7212 codec.
This series includes:
- CPG clock binding update for optional audio clock inputs
- CPG driver support for RZ/G3E audio clocks and resets
- Audio clock input nodes for RZ/V2H family DTSIs
- R-Car Sound node for RZ/G3E SoC DTSI
- Board-level enablement: I2C1, Versa3 clock generator, audio
pinmux, and DA7212 codec on SMARC EVK
Audio configuration on SMARC EVK:
- Codec: Dialog DA7212 on I2C1
- Playback: SSI3
- Capture: SSI4 -> SRC0 -> DVC0
- MCLK: 12.288MHz from Versa3 clock generator
- Format: I2S, R-Car Sound as clock master
- SSI4 shares clock pins with SSI3 (shared-pin)
Changes:
v3:
- Splitout from v2 [1]
- No code changes
v2:
- Fix Rob's comment on maxItems not needed with items lists.
- Drop DMA ACK second cell from DT specifier
